A driver is in a critical condition after he lost control of his car and hit railings and traffic lights on the A33.

Traffic police are appealing for witnesses to the collision which happened at about 8.55pm on Sunday.

The car, a green BMW 5 Series estate, had just crossed over the M4 at Junction 11 and was travelling towards Reading when the driver lost control of the vehicle.

An ambulance took the injured driver to the Royal Berkshire Hospital but he was later transferred to the JR2 Hospital, in Oxford, where he remains.

A 20-year-old man, who was driving a Vauxhall Corsa, was arrested at the scene on suspicion of dangerous driving and was released on police bail until Friday, July 6.

Police would like to speak to anyone who may have seen the BMW before the collision or the crash itself. Officers are particularly keen to speak to a man who identified himself as a witness at the scene but left before police could speak to him.

Anyone with information should call PC Samantha Allen, at Three Mile Cross traffic base, on 101 or Crimestoppers anonymously on 0800 555 111.
